Filed: 2008-09-02
Abstract: L'invention concerne un procédé de polymérisation d'éthylène, un catalyseur employé dans ce procédé, un procédé de fabrication employant le catalyseur et un produit fabriqué au moyen du procédé. L'invention concerne plus particulièrement un procédé de fabrication d'un copolymère d'éthylène à partir d'éthylène et d'un comonomère d'alpha-oléfine, le copolymère d'éthylène fabriqué ayant une distribution de masse moléculaire multimodale, une excellent aptitude au traitement, d'excellentes propriétés physiques et pouvant par conséquent augmenter la valeur et la productivité de produits tels que des tubes et des pellicules. Le copolymère d'éthylène fabriqué a une distribution de masse moléculaire ou de densité au moins trimodale. Par conséquent, lorsque le copolymère fabriqué est un copolymère linéaire faible densité, celui-ci permet d'augmenter considérablement la résistance aux impacts de pellicules, et lorsque le copolymère fabriqué est un copolymère d'éthylène moyenne densité, celui-ci peut être fabriqué sous forme de tubes présentant une faible vitesse de propagation de fissures et pouvant être employés à des températures élevées.

Title: Procédé permettant d'autoriser un ue à accéder de façon conditionnelle à un réseau central de paquets évolués
Inventor: RAJADURAI RAJAVELSAMY
IPC: H04B7/26
Filed: 2009-07-24
Abstract: La présente invention concerne un procédé permettant d’autoriser un équipement utilisateur (UE) à accéder de façon conditionnelle à un réseau central de paquets évolués (EPC), lorsque l’UE demande l’accès au réseau EPC à l’aide d’un réseau d’accès non-3GPP. Le réseau EPC extrait l’identité de l'UE, vérifie son identité à l’aide de l’enregistreur d’identité d’équipement (EIR) et autorise alors l’UE à accéder au réseau EPC en fonction de la vérification de l’identité du dispositif de l’UE. L’identité du dispositif est récupérée en utilisant les paires de valeurs d’attribut (AVP) des messages EAP, les AVP peuvent être des AVP EAP spécifiques au fournisseur. L’identité du dispositif de l'UE peut comprendre un code IMEI de l’UE comme première identité de dispositif ou une seconde identité de dispositif, qui est basée sur un type d’accès au réseau par l’UE. Le réseau EPC, suite à la vérification de l’identité de dispositif de l'UE avec l'EIR, autorise l’UE à accéder au réseau EPC lorsque la vérification a permis d’établir que l’UE est un dispositif de communication autorisé ou refuse l’autorisation à l'UE d’accéder au réseau EPC lorsque la vérification a permis d’établir que l’UE est un dispositif de communication non autorisé.
